Modelling from 1 object or more?
A Simplified Sample 

One mesh for the body of the container.  Cap not included.



Above in a progression of left to right, top to bottom


Blue Cube Scaled
Yellow  Loop Cuts
Blue with faces deleted in the Handle area .. dark back faces
Yellow [Bridge Edge Loops] so the handle with internal edges are present
Blue Spout trough and crests with [Proportional Edit]
Yellow with Subdivision Surface Modifier which smooths the corners in this example.
For the round spout use [Extrude] and the add on ... Loop Tools.  That should be a different question.  Not shown in the above example.
Extrude will be useful for decorative ridges.  Not shown.


The above has no detailed instructions since a Video Tutorial would be an efficient use of time for someone very new to Blender. This was mentioned in the comment. This proposed answer is not a tutorial. It can serve as a discardable practice model.  Blender Stack Exchange is not focused on artistry, but rather technique, question and answer.  I am sure you can be more artistic in your work than the simple model above.  Inspect and Improve the sample.
